Application filed September 12, 1921. Serial No. 500,050. i

To all whom t may concern.' l

Be it known that I, WILLIAM MoCRoRY, a citizen of the United States, residingvv at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Ironing Board, of which the following is a specification. f c

This invention relates tol ironing boards and relates particularly to ironing boards having relatively small boards attached.

It is the object of the invention to .provide an ironing board having an opening wherein an auxiliary board of relatively small dimensions is normally stored flush with the top ofthe main board, said auxil-v iary board being adjustablefor use -to an elevation above the main board, and locking lmeans being provided for maintaining such raised positie-11.

In attaining this object the invention contemplates providing a seat for the auxiliary board within the opening of the-*main board, and toggle arms fory supporting the auxiliary board inraised position, which arms are normally concealed-beneath the main board, and a handle-controlled latch mechanism engageable with the toggle arms in raised position to positivelyv maintain said position'.

A preferred embodiment of the invention is .hereinafter described and illustrated in the accompanying drawings, wherein,

Fig. 1 is a view in side elevation of the improved board with the auxiliary board in stored position.

Fig. 2 is a longitudinal vertical section of the same, showing the auxiliary board ele` vated for use.

Fig. 3 is a bottom view of the invention with the auxiliary board stored.

Fig. 4 is a cross-section taken on line 4 4 of Fig. 3. i

In these views the reference character 1 designates an ironing board having substantially the usual shape anddimensions, and having the central opening 2. Said opening is adapted to receive a relatively small auxiliarv board 3, of lesser thickness than the main board, the latter being formed marginally of the opening 2 with a seat 4 for said auxiliary board. When engaged with the seat, the auxiliary board is substantiallyflush with the top of the mainboard, as is best illustrated in Fig. 4. To permit the auxiliary board to be raised, when desired, to the position of use shown in Fig.

A2, there is employed a toggle 'mechanisme comprising apair of .legs 5 pivotally-attached to each'end of the board 3, there beneath, as bythe brackets 6, and corresponding links 7, which-are terminally pivotally connectedv respectively to the lower' ends of the legs 5 and to a pair ofy brackets 8, centrallydepending from the main board, at each side ofthe'opening 2. Bracerods 9 rigidly connect the links 7 extending from each pair of legs 5Jl When .the auxiliary' board is in lits storedposition the legsL 5 and links 7 are l positioned beneath the -main board, forming with each other an angle of approximately forty-five degrees, as shown in Fig. 1. When, however, the auxiliary board is elevated for use, as is seenin Fig. 2, the legs 5 project for the greaterv portion of their lengths above the board `1, and the links7 extend slightly, upward from the brackets 8 to ksaid legs Thus-the anglesbetween said legs and links is somewhat in excess of ninety degrees when Vthe auxiliary board is raised.' Notches 10l and 10 arerespectively formedin the pivotally connected ends of the legs 5 and links 7, whichnotches are invregistration when the auxiliary board is in yraised position. f To maintain said raised position there is transversely mounted beneath each end of the board a shaft 11,

carrying rollers 12, respectively engageable with the registering notches 10 and 10. Said shafts are each terminally journaledin plungers` 13 slidable lengthwise of the boardl in bracketsv 14secured to the bottom of said board ateach side of the opening 2therein. f

13, the response of said shafts to said springs being limited in the normal or lowered position of the small'board by engage `ment of the rollers 12 with the upper portions of the legsv 5 and in the raised position of said board by engagement of said rollers in the notches lOand 10 of the' legs 5 and links 7. Shifting ofthe auxiliary board eitherl from its raised to its lowered position, or vice versa, involves a retractive movement of the shaftsll which movement is yieldably resisted by the springs 15,

When pressure is upwardly applied to the` small board 3, for the purpose of raising the same,` the resistance of the springs 15 is overcome gradually, as the legs 5 ride up upon-the rollers 12, so that elevation of the board may be accomplished with. slight manual eiliort. Lowering oit the ai'lxiliary board, however, requires the exertion or a considerably greater downward pressure,

since the retraction of the shafts ll must be abruptly accomplished.

F or locking the toggle mechanism coinprised by the legs 5 andlinks .7, so as to positively hold the auxiliary board in its raised position, there is provided a mechanism comprising; a crank-shaft 16j ournaled transversely below lthefboard l `inthe brackets 8, and a pair of pull rods l?, oppositely eX- tending from the reverse crank throws 18 of said rshaft and respectively terminally engaging the shafts ll. A:reterably the yrods 17 are passed transversely rthrough the shafts 1l, and arevengaged beyond the latter by nuts 19 adjustableto vary the relation of said pull rods and shafts. r-irhe crank-shaft 16 is bent at one end to form a handle as indicated at 20, said handle projecting -normally downward as yindicated in Fig. l. When, after establishing the auxiliary board in elevated position, it lis vdesired to lock Said board in said position, it is necessary only to rock the sha-ift l@ to the position shown in Fig. 2, in which position the crank throws i8 are substantially horizontal, establishing an overlapping relation between the adjacent'ends oi the pull rods i7 and stress-- ingthe shafts 11 toward each other so as to firmly press the rollers l2 into the notches 9 and y10 of the legs 5 and vlinks 7. llhen the auxiliary board ,8 is thus held in raised position, the upper ends of the. legs 5 bear against the brackets 6 in such a manner as to insure against swinging of said legs. Unlocking is enected by merely Swinging the handle 2O back to its normal vertical position., i

V Alt is to be understood .that raising or lowering of the auxiliary lboard is .effected by the e'lort ot the springs l5 will maintainl said auxiliary board raised, under the stresses ordinarily pla-ced upon Said board in use, it is preferred to employ the described locking mechanism so as to positively safeguard theauxiliary board against accidental dropping.

The described invention makes lthe tnll sized board orthe auxiliary board for small work available lalternatively .without waste ottime, andina desirable compact form.

-What l claim is: 1

l. ln a device of the'character described, the combination with anr ironing board 'formed with an opening, ot a yrelatively small ironing board fitting normally'within said opening, and removable from said opening to an elevated position of individual use above the main board, means for supporting'the small'board upon vthe'main 'board in the elevated position otfthe former, and spring means yieldably resisting movement of the small board from. either ofi its two positions to the other one.

2. 'ln 4a device ot the character described, the combinationk with an ironing board formed with an opening, of a relatively small ironing board tting normallywithin said opening, and removable liromsaid opening to an elevated position of individual use above the main board, and a toggle mechanism for lsupporting the sinalleiboard in its elevated position, comprising a pair or legs pivotally connected to the smaller board one at each end thereof, and links having their ends pivoted respectively to said legs and to the middle portion ol the main board.

In testimony whereof l sign `this specification.
